MLA 18-88 - Mineral Resources Of The Carson-Iceberg Wilderness Study Area, Alpine County, California

In 1986 and 1987, at the request of the U.S. Bureau of Land Management, the U.S. Bureau of Mines studied the 550-acre Carson-Iceberg Wilderness Study Area (NV-030-532), in order to evaluate its identified mineral resources. The Wilderness Study Area is located in Alpine County, CA, 11 mi southeast of Markleeville, CA. Tertiary volcanic and granitic rocks, as well as alluvium, underlie the area. Hydrothermal alteration and faulting have affected some rocks; argillic, silicic, and limonitic alteration are found, particularly near faults. No mineral resources were identified in the Wilderness Study Area. The area has one small pit and no mines or claims. Samples from the Wilderness Study Area and vicinity contained uneconomic amounts of gold, silver, copper, lead, zinc, mercury, arsenic, and molybdenum. Mineral occurrences are too small and low grade to be of interest within the foreseeable future.
